摘要
本文详细介绍了Ｋｉｒｃｈｈｏｆｆ方法，并且针对具体计算模型作了相应修改，在求解直升 机旋翼流场的基础上，预测了旅翼在悬停状态下的高速冲击运场噪声，计算结果与理论分析 一致，体现出旋翼ＣＦＤ与Ｋｉｒｃｈｈｏｆｆ方法相结合的良好应用前景。
A combined Euler/Kirchhoff method is presented for predicting high-speed impulsive noise generated by a hovering rotor blade. Although lacking experimental verification. the results are promising. The results show that some benefit can be made by taking thin、sweep and taper blade-tip Shape in reducing the far-field noise. The modification is made. It is shown that the combined Euler/Kirchhoff scheme provides a powerful tool for engineering purposes.
